The String of Spades (Ceropegia woodii ‘String of Spades’ or ‘Heartless’) is a trailing succulent. Its unique appearance features dark green, spade-shaped leaves, often mottled with silver or cream-colored veins, and sometimes tinged with reddish undersides. This plant’s cascading growth makes it a popular choice for hanging baskets in indoor spaces. It is easy to care for, appealing to both novice and experienced plant enthusiasts.
Core Care Requirements
Light
String of Spades thrives in bright, indirect light. Place it near an east or west-facing window for gentle morning or late afternoon sun. A few feet from a south-facing window with a sheer curtain can also provide sufficient filtered light. Insufficient light results in sparse growth and dull leaf color, while too much direct sunlight can scorch the leaves.
Water
Water String of Spades using a “soak and dry” approach. Allow the soil to dry out completely between waterings to prevent root rot. Check soil moisture by feeling the top inch or two; if dry, it’s time to water. Overwatering leads to mushy stems and yellowing leaves, while shriveled or crispy leaves indicate underwatering. Water less frequently during winter when growth slows.
Soil
The String of Spades prefers a well-draining, airy soil mix. A succulent or cactus potting mix is recommended. If using a regular potting mix, amend it with perlite, coarse sand, or horticultural charcoal to enhance drainage and aeration. Good drainage prevents water accumulation around the roots, which can lead to root rot.
Temperature and Humidity
This plant prefers average room temperatures, 65-80°F (18-27°C). It is not tolerant of cold temperatures and needs protection from prolonged exposure below 55°F (13°C). String of Spades thrives in average household humidity, around 40-50%. Avoid excessively dry or overly humid conditions, as the latter can encourage fungal issues.
Fertilizer
Fertilize your String of Spades sparingly during its active growing season (spring and summer). Use a balanced liquid fertilizer diluted to half strength. Applying fertilizer once a month or every few months during this period is sufficient. Avoid fertilizing during the plant’s dormant period in fall and winter or immediately after repotting, as this can damage the roots.
Propagation and Maintenance
Propagation
Propagating String of Spades is straightforward using stem cuttings. Take a stem segment with a few leaf nodes. Remove lower leaves to expose the nodes. Cuttings can be rooted in water, with roots appearing within a few weeks, or directly planted into well-draining soil. Propagate during the plant’s active growing season.
Maintenance
String of Spades is a slow-growing plant that requires minimal pruning. Prune to maintain shape, encourage bushier growth, or remove leggy stems. Regularly removing dead or yellowing leaves also helps maintain the plant’s overall health and aesthetic appeal.
Troubleshooting Issues
Common issues with String of Spades have clear indicators. Yellowing or mushy leaves point to overwatering, meaning the soil stays wet too long. Shriveled or crispy leaves indicate underwatering. Adjust watering frequency based on soil dryness. Sparse or leggy growth, characterized by long gaps between leaves, signals insufficient light. Move the plant to a brighter location with indirect sunlight for denser foliage. While pest-resistant, String of Spades can encounter mealybugs or spider mites. Regular inspection and prompt treatment with insecticidal soap or neem oil manage infestations.
